براغي رأس مقبس M10-1.5 × 12 مم | محرك مقبس سداسي منخفض الرأس | ملولب بالكامل | فولاذ سبائكي فئة 10.9 مع أكسيد أسود حراري (100 / عبوة)

Bought these for a jig I was building, and the 12mm length was spot on for the plate thickness. The black oxide coating seems to hold up well against shop fluids. Good quality for the price.

The hex socket drive seated perfectly with my Allen key, no stripping even at torque. The thermal black oxide finish feels slick and corrosion-resistant, and threading was clean all the way down. These are solid for precision assemblies.

I needed some fasteners for a custom jig setup and the black oxide finish on these is even and clean, no flaking bits. The 12mm length was just right for a tight clearance on my tooling plate.
